a friend of mine tells me about a run down building that has history and a great atmosphere that would make a great haunt. however she keeps telling me how run down it is..keeping in mind i have yet to see this place. my questions:

how much money do you think should be invested in reparing a place to make a haunt. what sort of things should i look for in a run down building?
(can i board up windows and still keep the fire marshall happy?)
